- in one embodiment a longitudinal groove (5) and in another embodiment a longitudinal flange (29), and

- two longitudinal holes (6),

- a cover (7) for the longitudinal adjustment piece (3) located at one end of the longitudinal adjustment piece (3), which prevents the threaded piece (2) from coming out of the inner housing (4) of the piece longitudinal adjustment (3), and

- a sleeve (8) for the longitudinal adjustment piece (3) comprising:

- a housing (30) for the longitudinal adjustment piece (3),

- in one embodiment a longitudinal flange (9) that is complementary to the longitudinal groove (5) of the longitudinal adjustment piece (3), such that the longitudinal flange (9) and the longitudinal groove (5) prevent a relative rotation between the piece of longitudinal adjustment (3) and the shirt (8); and in a second embodiment a second longitudinal slot (20) complementary to the longitudinal slot (5) of the longitudinal adjustment piece (3) such that a pin (18) inserted between the second longitudinal slot (20) and the longitudinal slot (5 ), or the longitudinal flange (29) prevent a relative rotation between the longitudinal adjustment piece (3) and the sleeve (8);

- two through holes (10) configured to be located in correspondence with the longitudinal holes (6) of the longitudinal adjustment piece (3) and as two screws (11) are screwed to a greater or lesser extent on the longitudinal holes (6) of the trim piece longitudinal (3) the relative position of the sleeve (8) and of the longitudinal adjustment piece itself (3) is modified, adapting its relative position according to different lengths of the steering axis (1), and

- a perimeter rim (12) comprising a plurality of through holes (13).

The threaded part (2) of the steering system for a boat object of the invention can be a nut or a screw, depending on whether the steering shaft (1) of the boat has a male end or a female end.

The preferred embodiment of the longitudinal adjustment piece (3) is a keyed cylinder, but the outer shape of the longitudinal adjustment piece (3) can be any that meets the requirement that the outer shape of said longitudinal adjustment piece ( 3) and the internal shape of the housing (30) of the sleeve (8) are complementary so that there is no relative rotation between the longitudinal adjustment piece (3) and the sleeve (8).

The cover (7) of the longitudinal adjustment part (3) performs the function of extracting the steering system object of the invention from the axis, since when unscrewing the threaded part (2) from the axis of the boat, being located in the interior of the housing (4), makes contact with the cover (7) forcing the extraction of the system object of the invention with respect to the axis, without the need to use a bearing extractor of those known in the state of the art and that can damage the steering system itself.

The steering system object of the invention comprises a motor with a rotor (16) and a stator (17) such that the stator (17) is fixed to a casing (19) which, in turn, is fixed to the boat ( 14) and the rotor (16) is fixed to the perimeter rim (12) of the sleeve (8), with this configuration the steering system object of the invention has the capacity to rotate the steering shaft (1) of the fishing boat. motorized way.

The motor of the steering system object of the invention is housed inside the motor casing (19) which, in the preferred embodiment, comprises a part on the boat side (19a) and a part on the steering wheel side (19b), such that the part on the boat side (19a) is fixed to the stator (17) of the motor, the said part on the boat side (19a) being fixed to the boat, and the fixing of the two parts (19a, 19b) leaves the motor inside leaving view of the central part of the rotor (16) where, as explained later In this description, a steering wheel (26) is fixed. The limitation generated by the fixing of the boat-side part (19a) prevents the rotation of said boat-side part (19a).

The steering system comprises a battery (15) configured to drive the motor, in addition to the electronic part that is explained below, and thus make the steering shaft (1) of the boat rotate.

The steering system for a boat that is the object of the invention comprises, in addition to the battery (15), a wireless communications module (23), and a control unit (25), configured to receive a control order through the control module. communications (23) and activate the motor according to the received control order. In addition, it can comprise a geolocation module (22) to repeatedly obtain the positioning of the system, such that the control unit (25) is configured to follow a route based on the control order and the positioning obtained by the geolocation module. (22).

The battery (15), the wireless communications module (23), the control unit (25) and the geolocation module (22), if the system has one, are located inside an electronics casing (21 ) that is located between the motor casing (19) and the fixing means to the boat (14), so that the motor casing (19) is fixed to the electronics casing (21) which in turn it is fixed to the boat by means of fixing to the boat (14).

The electronics casing (21) is also made up of a part on the boat side (21a) and a part on the steering wheel side (21b), such that the union of the two parts (21a, 21b) causes them to be housed inside the electronics casing (21) the aforementioned elements. The limitation generated by the fixing of the boat-side part (21a) prevents the rotation of said boat-side part (21a).

The steering system for a nautical vessel object of the invention comprises fixing means to the vessel (14). The fixing means to the boat (14), in one embodiment of the invention, comprise a first strip of fabric fixed to the electronics casing (21) and a second strip of fabric fixed to the boat by adhesive or any other method. , such that the first strip of fabric and the second strip of fabric engage when they come into contact. In another embodiment, the means for fixing to the boat (14) comprise a plate for fixing to the boat that It comprises a central hole configured to allow the steering axis (1) of the boat to pass through, such that said fixing plate is anchored to the external hydraulics of the boat by means of three screws that are common in said external hydraulics of the boat. (see figure 10) or by adhesive.

There are other embodiments of the fixing means to the boat so that either by friction or by mechanical fixing, for example, a tongue and groove, the relative rotation between the electronics casing (21) and the boat is prevented.

In another embodiment, the fixing means to the boat (14) comprise a suction cup, such that said suction cup is anchored to the panel of the boat by suction at its base, and is fixed to the electronics casing (21) at its upper part. by means of an arm adjustable in length.

The control order that the control unit (25) receives through the wireless communications module (23) can be sent through an application of a smart mobile device or a computer, so that through the geolocation module (22) the It repeatedly obtains the position of the system to be able to follow a marked route, also considering the information of the control order.

Finally, the steering system for a boat object of the invention comprises the steering wheel (26) fixed to the rotor (16) by means of screws (30) inserted in a plurality of housings (29) located in the rotor (16) of the engine.
